Brunei's polymer series began in 1996 under the Currency Board, but the transition to AMBD as the issuing authority in 2011 brought a fresh issuance of the same basic designs without a fundamental redesign — continuity of imagery under a rebranded institution. Note Printing Australia has supplied Brunei's polymer notes consistently since the late 1990s, making this one of the longer-running NPA contracts in Southeast Asia.

The polymer substrate here is the Australian-developed Guardian material, which in Brunei's tropical humidity has proven considerably more durable than the cotton-paper notes it replaced. The 2011–2013 date range on P#37 reflects print batches rather than any policy or design change.
